John Gibbons is best known for his time as a manager in Major League Baseball, particularly with the Toronto Blue Jays. Before stepping into the managerial role, Gibbons had a career as a player, though it was relatively brief at the major league level. Born on June 8, 1962, in Great Falls, Montana, Gibbons grew up in a military family and spent much of his youth in San Antonio, Texas. He was drafted by the New York Mets in the first round of the 1980 MLB Draft, selected 24th overall.

Gibbons' playing career as a catcher was primarily in the minor leagues, though he did have a stint in the majors. He made his MLB debut with the Mets in 1984. During his time as a player, Gibbons struggled to find a permanent spot on the Mets' roster, largely due to injuries and the presence of other established catchers. His major league playing career was limited to 18 games over parts of the 1984 and 1986 seasons, during which he recorded a .220 batting average with one home run and two RBIs.

After his playing days ended, Gibbons transitioned into coaching and managing, where he found a more enduring role in baseball. He began his coaching career in the Mets' minor league system, where he served in various capacities, including as a manager for several of their minor league affiliates. His managerial skills and understanding of the game eventually led him to the Toronto Blue Jays organization.

Gibbons first joined the Blue Jays as a bullpen catcher in 2002, and by 2004, he was named the team's manager. His first tenure as the Blue Jays' manager lasted until 2008. During this period, Gibbons was known for his straightforward approach and ability to handle a diverse clubhouse. However, the team did not make the playoffs under his leadership, and he was dismissed in June 2008.

After leaving the Blue Jays, Gibbons continued to work in baseball, including a stint as a bench coach for the Kansas City Royals. In 2013, he returned to the Blue Jays as their manager, a move that surprised many in the baseball community. His second tenure with the team proved to be more fruitful. Under his guidance, the Blue Jays ended a 22-year playoff drought by reaching the postseason in 2015. That year, the team advanced to the American League Championship Series, where they were defeated by the Kansas City Royals. The following year, the Blue Jays again made it to the ALCS, this time losing to the Cleveland Indians.

Gibbons was known for his laid-back demeanor and his ability to connect with players, earning their respect and fostering a positive team environment. His managerial style was often described as player-friendly, and he was appreciated for his honesty and straightforward communication.

In 2018, Gibbons and the Blue Jays parted ways after a challenging season. He left the team with a managerial record of 793 wins and 789 losses over his two tenures. While his time as a manager did not include a World Series title, Gibbons is remembered for leading the Blue Jays back to relevance in the mid-2010s and for his steady leadership during a transformative period for the franchise.
